Before I saw all these comments I had figured out that it was auto and ponies also and that the two notes are indeed written by the same person and it isn't "amen" but the author's last name. His forst name appears to be Arthur. So the last name might be Arnen or Armen. It appears Titus should have known better than to ride one of those "old trots" because he broke the poor beasts ribs in doing so. He needs a car! Poor pony!

I did a little google search. There is indeed a company that makes "aristo" technical and mechanical pens and pencils, fountian pens and drafting supplies. Me and my broken down little pony feel properly chagrined, LOL. Although for a person who uses quality writing implements, Arthur certainly has lousy penmanship. :-)
